HENRY CLAYTON, OF PHILADELPHIA, PENNSYLVANIA.

AN ESTH ETlO-IVIASK.

SPECIFICATION forming part of Letters Patent No. 787,828, dated April18, 1905.

Application filed October 11 1904. Serial No. 228,002.

To fI/Z Z who/It fl may concern:

Be it known that l, TIENRY CLAYTON, residing at Philadelphia, in thecounty of Philadelphia and State of Pennsylvania, have invented certainnew and useful Improvements in Anesthetic-Masks, of which the followingis a specification.

M y invention relates to certain new and useful improvements inanesthetic-n1asks, and more particularly seeks to provide a mask of thischaracter of a very simple, du-

rable, easily-operable, and cheap construc tion which will readily andeffectively serve its intended purposes.

In its generic nature my invention includes a wire cage or frame adaptedto re eeive a cloth or other absorbent material and means for securelyholding said cloth or other absorbent material to said cage, which meanscan be easily and quickly attached to or detached from the frame toallow for the removal of the cloth, as well as to permit the thoroughcleaning and sterilizing of the mask. 7

\Vith other objects in view, which will be hereinafter apparent, theinvention also includes certain novel construction and arrangement ofparts, all of which will be first described in detail and thenspecifically pointed out in the appended claims, reference being had tothe accompanying drawings, in which Figure I shows my invention asapplied for use. Fig. 2 is a perspective view of my invention, the clothbeing removed. Fig. 3 is a vertical longitut'linal section thereof, thecloth being shown in position in dotted lines. Fig. l is a detail faceview of a portion thereof. Fig. is a detail cross-section on the line 55 of Fig. 3. Fig. 6 is a plan of a slightly-modi'fied form of myinvention. Fig. 7 is a detail cross-section on the line 7 7 of Fig. 6.Fig. 8 is a detail plan view of another modification of my invention.Fig. 9 is a similar view of a further modification of my invention. Fig.I0 is a detail cross-section on the line 1U 10 of Fig. 9.

Referring now to the accompanying drawings, in which like numerals andletters of reference indicate like parts in all the figures, and byparticularly referring to Figs. 1 to 5, which illustrate the preferredform of my invention, it will be seen the cage or frame A consists ofawire base member 1, bent into the desired shape and comprising the bodyportion 1, the neck portion 1", and the finger-engaging portion 1 Theneck portion 1" is provided with S-shaped bends l" 1, arranged parallelwith each other to form a locking-momber-receiving portion for thepurpose presently explained. The neck 1 terminates in a bent member orbook portion 1, as clearly shown in Figs. 1, 2, 3, and 4. The basemember 1 is composed of a single piece of wire bent into the desiredshape, and the ends thereof are secured together, as at 1, by welding,soldering, or any other suitable means.

1" designates the finger member for readily permitting the lockingmember 3, hereinafter again referred to, to be released from the cagemember to allow of the removal of the fabric.

2 2 designate a plurality of wire members bent into a semicircular shapeand disposed parallel in pairs to form the fabric-receiving or cageportion of the mask, and the said members 2 2 are secured at their ends2 2 to the frame member 1. by being bent around the same, and the saidends may be welded, soldered, or otherwise made fast to the member 1.

The wire members 2 2 where they are sccured to the base 1 are bent toform locking-shoulders 2 2 for the purpose presently explained.

3 designates what I term the locking memher, and the said member 3consists of a wire member bent into substantially the same shape as thewire member 1, and the said wire member 3 is bent to form engagingbearing portions 3 3, merging with angled portions 3 3 to cooperate withthe S-shaped bends l 1 of the member 1, whereby to form, as it were, ahinged connection between the members 1 and 3, as clearly shown in Figs.2, 3, and 4 of the drawings. The wire 3 has its ends joined, as at 3, bywelding, soldering, or otherwise in the same manner as the ends of thewire 1 are joined.

So far as described it will be seen the fabric 0 is first placed on thecage A, (see Fig. 1,) after which the locking member 3 is placed inposition with its bearing portion 3 interlocked with the S-shaped bentportions 1", (see Figs. 2 and 3,) and the said member 3 is then sprungover the wires 2 2 until the locking member 3 passes the shoulders 2 2and abuts against the end 2 of the said member 2, as is clearly shown inFig. 5. This securely holds the fabric C in position. The mask is thenplaced over the mouth and nose of the patient in the manner shown inFig. 1 and saturated with a suitable anesthetic by dropping the sameupon the fabric from any suitable dropping bottle or receptacle. Theportions 3 3 of the locking member 3 serve to prevent lateraldisplacement of the said member 3 with respect to the member 1.

In Figs. 6 and 7 I have shown a slightlymodified form of my invention,in which the member 1 is provided with S-shaped bent portions 1 1 whichare arranged in a horizontal plane instead of vertical planes, as is thecase in Fig. 1. In this form of my inven tion also the locking member 3does not have its ends joined together, as is the case in the preferredform of my invention; but the said member 3 has its ends bent to formhooks 3 3 which hooks cooperate with the bearing portions of theS-shaped bends 1 1. In this form of my invention the finger-piece 1 isnot formed in the member 1, but the locking member 3 is provided with afingerpiece 3", as shown, and for the same purpose as the finger-piece 1in Fig. 2. V

Fig. 8 shows a still further modification of my invention, which issubstantially the same as that shown in Fig. 6, excepting that the partsare of a different shape. The locking member 3 in this form is alsoprovided with hook portions 3 3 to cooperate with ghe S-shaped bentportions 1 1 of the mem- In Fig. 9 I have shown a further modificationof my invention, which is generically the same as that shown in Figs. 6and 8, with the exception that in Figs. 6 and 8 the S-shaped portions 11 are formed at the junction of the neck portion 1 with the bodyportions 1, while in Fig. 9 the body member 1 where it joins with thefinger-piece 1 is bent to form bearing portions 1 1 to receive the hookends 3 of the locking member 3, and in this form of my invention thelocking member 3 has a hinged connection with the member 1, as has alsothe locking member 3 in the form shown in Figs. 6 and 8.

By detachably holding the locking member 3 to the member 1 the saidlocking member can be readily detached from the member 1 to allow of theparts being thoroughly sterilized and cleaned. i

From the foregoing description taken in connection with the accompanyingdrawings, it is thought the complete construction, operation, and manyadvantages of my inven tion will be readily apparent to those skilled inthe art to which it appertains, and I desire it understood thatslightchanges in the detail construction and arrangement of parts may be madewithout departing from the scope of the invention or that of theappended claims.

Having thus described my invention,what I claim, and desire to secure byLetters Patent, is-
